The application provides a
data scheduling method and device and
electronic equipment. The embodiment automatically identifies a cold
unit memory (referred to as a cold
unit memory) in a first memory, whose
access frequency per unit time is less than a first set threshold, and a hot
unit memory (referred to as a hot unit memory) in a second memory, whose
access frequency per unit time is greater than or equal to a second set threshold, automatically schedules data in the hot unit memory in the second memory to move to an idle unit memory in the first memory, and automatically schedules data in the cold unit memory in the first memory to move to an idle unit memory in the second memory, so that data with high
access frequency is stored in the local first memory of the
system, and data with low access frequency is stored in the second memory which is expanded, the advantages of local memory high-speed access and memory capacity expansion are maximized, and the
data access efficiency is improved.
